(Z)-2-(2-Acetyl-2H-isoquinolin-1-ylidene)acetamides have been synthesized from 2-vinylbenzonitrile derivatives in three steps. The key step involves the iodine-mediated 6-endo cyclization of (Z)-3-acetylamino-3-(2-vinylphenyl)propenamides, which are prepared by the coupling of 2-vinylbenzonitriles with magnesium enolates of tertiary amides followed by N-acetylation.
(Z)-2-(2-乙酰基-2H-异喹啉-1-亚基)乙酰胺已通过三步法从2-乙烯基苯甲腈衍生物合成。关键步骤涉及碘介导的(Z)-3-乙酰氨基-3-(2-乙烯基苯基)丙烯酰胺的6-endo环化反应,这些化合物是通过2-乙烯基苯甲腈与叔胺的镁烯醇盐缩合,随后进行N-乙酰化反应制备的。
